While the construction of the present inven- ,tion may be` adapted for various applications it is particularly suited for embodiment` in paper containers `or containers ofbrous material. The invention maybe embodied in containers for holding cosmetics, food stuffs, liquids, pastos, powders and many other products and may be embodied in `containers of various shapes and proportions. I- p The container construction ofthe present invention illustrated in Figs. 1 to 4, inclusive, of the drawing, comprises, generally, a containerbody resistant to the material which the container is intended to hold.

The bottom or lower closure I I may be fixed or Y seamed to the body HJ before ythe container is` supplied to the packager. However, when a frangible closure or sealis provided for the container to be Within or under the top closure, as described and claimed in mycopending application Serial No. 64,031, the bottom closure I I may be only partially seamed to the body I!! when the container is supplied to the packager so that it may be easily removed to permit filling of the con- .tainer and then replaced for final scanning to kvthe container body. The closure II includes a .l disc-like head It of paper, pressed paper, cardboard, or similar fibrous material. The head I6 may be treated or coated to resist the action of the material for which the container is intended.

Further, the top closure of the container ID is formed and shaped to give the vcontainer a pleasing appearance and to at it is the top closure or`cover o f the container. i

The sealing head I2 of the top closure may be similar to or identical with the above described head I6 of the bottom closure II. The head I2 is al disc shaped member thatrnay be formed of paper, pressed paper, cardboard, or other fibrous materials. If desired or necessary the head I2 may be coated, treated or lined to be fluid-tight or resistantto the material held in the container I0. The major portion of the head I2 may be 4flatas illustrated, although if desired,the head maybe corrugated or embossed. The peripheral portion of the head I2 is shaped to cooperate with the upper end part of the body III. An upwardly or outwardly projecting annular flange 25 is provided on the head I2 and` is adapted to cooperate l with the internal surface I8 of the body IB. f The flange 25 is preferably flared upwardly and outwardly to tightly or frictionally seal ,with the inprovided with a laterally or outwardly projecting vrim 26. The rim 26 is annular or continuous and project outwardly beyond the external surface of the body I0. The lower side of the rim 733 is adapted to rest downwardly against the upper It will be observed that both tion or engagement with surfaces ofthe nbrcus container body I0. As the container body I@ and the Ahead I2 are both formed of brous material, this cooperation assures an effective seal and a desirable frictional engagement in the case where the closure forms a removable and replaceable cover. f

The outer head lor disc I3 is provided to increase the thickness of the cover or top closure, `to add to the strength of the closure, to protect a frangible inner seal (not shown) when such a seal is" employed, and to give the closure a pleasing appearance. 'I'he disc i3 may also serve to carry a label or ksuitable ornamentation and to provide a substantially flush upper surface for the container. In practice the disc I3 may be formed of any suitable material, for example, it may be formed of sheet metal, cardboard, paper, pressed paper, or` any other suitable material. In the `present disclosure the disc I3 may be considered as formed of fibrous material. The disc I3 is proportioned` so that its periphery is spaced inwardly from the internal surface of the head flange 25. The disc I3 may be given any desired vornamental configuration. In the typical case illustrated the disc I3 is domed or shaped to present a smooth convex external surface and a smooth concave inner surface.

It is to be understood that the disc I3 may be other shapes, for

example, it may have graduated annular terraces and steps, corrugations or embossing of various kinds, etc., or it may present a concave upper surface.A 'Ihe disc I3 overlies the head I2 and is preferably in spaced relation to the head.

The spacer Ill may be a washer-like ring of solid f cardboard, felt or the like or may be a double or single faced corrugated board. ring as illustrated.

The spacer le. lies against the upper surface .of the head I2 and has. its peripheryin spaced adjacent relation to the flange 25. The peripheral portion of the disc i3 is adapted to rest against the upper surface of the spacer. I4. The spacer I4 may be adhesively secured to the `head I2 or the. disc i3 or both. This is not necessary, however, as the seam ring I5 holds the several parts of the `closure assembly `in the proper relation without resorting to the use of adhesive.

. The seam ring I5 serves to hold the several parts of thetop closure together to forni a unitary structure, to hold the flange inshape to .Jfrictionally engage and seal with the internal t vention, the ring I5 has a substantially cylindrical inner part 2S that engages or bears outwardly against the internal surface of the flange H5.. `The `ring part 28 is tubular `or extends axially with relation to the longitudinal axis of the container body Hl and has its inner edge or `end resting against the upper surface of the head' I2. The ring part 28 is of sufficient extent or lengthto extend outwardly to or adjacent the outer surface ofthe spacer Ul. The periphery of the spacer ld preferably cooperates with the ring part 28 and this cooperation holds the spacer I4 centralized.

Itis an` important feature of the invention that `the seam ring I5 cooperates with the disc I3 to hold the same against outward movement and displacement. The ring I 5 is provided with what I will term an inturned flange 29. The ange 29 is an integral part of the ring I5 and is formed by bendingor crimping the metal of the ring.

The irl-turned flange 29 occurs at the upper end of the above described part 28 and projects in- `wardly therefrom relative to the central axis of l the containerbcdy Ml. The ange 29 is continuous or annular and overhangs and engages `against the peripheral portion of the disc i3.

The under side `ofthe flange `29 engages downwardly against the disc I3 and `being annular, has engagement with the disc throughout its circurnference.

the particular arrangement illustrated in the drawing the flange 29 slopes upwardly and inwardly to cooperate withthe upper peripheral corner of the disc I3. The invention is not to be construed as limited to this particular arrangef merit as the angle or slope of the flange 29 may be `varied to suit different conditions, for examplethe iiange 29 may be substantially hor1- aontal to engage downwardly againsty .the upper side of the disc I3 or may be pitched at; a sharp angle to lie substantially ush with the upper sur- `face `of the disc. It is to `be understood that the angle or pitch ofthe ange 23 maydepend upon the configuration of the disc I3 or upon the positionof the 4peripheral portionof the disc I3. In

any event the flange 29 isshaped or arranged to havev retaining..V engagementfwith the disc I3.

The flangeZQ engaging .downwardly against the peripheral portion of the disc i3 throughout its circumference holds the disc .I3 downwardly against the spacer I l to positivelyv prevent outward displacement ofthe disc and to `hold the disc against lateral shifting. Thek flange 29 preferably overlapsor overlies a substantial por-r f tion of the disc Iii to dependably retain the disc in place and prevent loss of the disc in the event of shrinkage, warping or distortion ofthe disc.

Ifldesired for any reason whatsoever, theflange 2Q and the spacer ld may be related so that the disc le may be turned with respect to the ring l5 and the head l2.y l

In the construction illustrated the rim 3@ `is substantially flat, it being understood that theyrim `3i] or a portion of the same may be curved or made convex or given any other configuration as desired. The rirn d@ engages inwardly or downwardly against the upper side of the rim 25. As initially formed the rim 3d is generally flat and of sufficient width to extend outwardly beyond the periphery of `the brous rirn 26. When the .f

ring 25 is searned to the head I2 the projecting peripheral portion of the rim 3l) is curled under to wrap orv engage about the edge portion of the rim 25 and to cooperate with the under side of the rim 25. Fig. 3 of the drawing best illustrates. 5|

The curled-under part 27. provides the top closure with a smooth round` metal peripheral surface .iat may be engaged or grasped for `the purpose of removing and replacing the closure. The rim 3d, shaped as just described to have the turnedunder part 2l, preventsfraying of the rim 23,

strengthens the rirn .26 and holds the rim in place for engagement with the upper end of the container body Ill. The rnajor portion of the rim 3l! maybe sloped or made slightly convex to conform generally to the slope or shape. of the domed disc lil so that the upper surface` of the closure asseinbly presents a smooth substantially flush,`

appearance. 4 l 1 The `rim il@ may be searnedA or curled to have its part Ill grip inwardly against the external surface of the body lil to secure or seam the top closure `to the container. By referring to Fig. 4

`it will be seen that the part 2d corresponds in location to part 2l .and itlwill be understood how the part 2l` may be curled or seamed to grip the wall the container body `Ill tightly. The engagement of the part il with the container body lil may be tight or firm or may besuch that the top closure may lcemanually removed from the container without the employment ofan opening device. 1f the top closure is intended to form a readily removable cover the rim 3l! and the part 21 may be left as illustrated in Fig. 3 ofthe drawing so that the closurelis held on the container through the frictional engagement of the ange 25 with the internal surface IS of the `body iti. and the frictional engagement of theI part 2l with the external. surface of the body I3;

With the rirn 35i and the part shaped as illus tratedin the drawing the peripheral portion of rim including the part El forms a conveniently engageable portion of thetop closure that may be graspedor engaged when removing and replacing the closure. .l

Itfis believed that the features ofv the form,

of the invention illustrated in Figs. ll' to 4 inelusive, of theldrawing, will be readily apparent from the'foregoing detailed description. It

u will be observed that the single metal ring I `serves to dependably retain the disc I3 in place, maintain the flange in condition for frictional engagement with the internal surface I3 of the body Ill, covers and strengthens the rim 25 for cooperation with the end of the body II), frictionally engages the external surface of the body toeither loosely or securely seam the closure to the body and forms a smooth rounded periphery for the closure construction and the ring part 28 serves to re-inforce and ,back-upA the brous Y' iange 2and to denitely locate ,the spacer I4.

It will be observed that the ring part 21B and the rimpart 21 are related so that the fibrous flange "25' and the body wall are 'frictionally gripped ybetween them and therefore the flange 25 is re- `inovably retainedin eiective sealing cooperation with the internal surface i8 of the body Ill.

The ange 29 holds the disc I3 against outwardk displacement and maintains the disc infirm engagement with the spacer I4. 'Ihe flange 23 overlaps the peripheral part of the disc` I3 to conceal its edge and to provide the assembly with a smooth substantially continuous outer surface.

The rim 3d with its turned-under part 2l sub-` stantially conceals the fibrous rim 7.6, braces and supports the rim 26, provides the rim 2E with a metal peripheral covering and either loosely or tightly engages the external surface of the container body I ll to loosely or tightly secure p the closure to the body by the engagement of the ange 25 With the interior of thebody and l trated in Figs. l to l@inclusive the frictional and gripping engagement of the 'part 21 with the exterior of the body l0.

Fig. 5 of the drawing illustrates a slight variation in the form of closure construction illus- In the construction shown in Fig. 5 the head I2, the disc I3 and the seam ring I5 may be the same as in the foregoing figures. The spacer I4 is eliminated and the inner part 28 of they ring I5 is crimped or distorted to have inwardlyy projecting lugs 3l cooperating Withthe under side of the disc I3 to holdthe disc in spaced relation to the head I2.

The lugs 3l arelcircumferentially spaced about the "part 23 to cooperate with the under surface of the disc I3 at a number of points. In this construction the ring `I5 serves to hold. the disc against both inward and outward movement.

board, pressed paper or other suitable materials.

'The major portionof the disc I3a may be domed as illustrated or may have any other desired shape. In accordance with this form of the invention the disc i3 has a down-turned or inturned peripheral flange 32. Theange 32 is an integral part of the disc I3SL and is continuous or annular. When the'lange 29 of the` metal l :ring i5 has the eonguration illustrated throughout the drawing, lthe peripheral corner of the disc |32 where the flange 32 joins the body of the disc is engaged by the 'under side of the ring ange 29.' This corner 33 of the disc I3a may be rfhe discr Ila may be formed of paper, cardinclined or sloped to'conformr to the pitch of the ilange 29 and if desired may be such that the uppersurface of the'disc I3a is flush with the upper surface ofthe rim 30. The cooperation oi"y the iiange 29 with the corner 33 dependably holds f the disc I3a against outward movement and displacement and firmly maintains the disc in place. The outer surface of the ilange 32 may cooperate with thelinner surface of the ring part 23 and this engagement may hold the disc I3a1' against` lateralv movement. The lower edge of' the flange 32 restson the upper sideof the head I2.` This engagement dependably holdsl the disc I3a against inward movement. Thus it will be seenv that the downwardly projecting flange V32` cooperates with the head I2 to hold the disc I3a in the'desired spaced yrelation to the head I2. The flange 32 is proportioned so that the corner 33 is engaged 'by the ring flange 29 when the` loweredge of the ange 32 rests on the head |25 It is to be particularly noted that the construction illustrated in Figs.` 6 and `8 of the drawing provides for the retention of the disc I3a against inwardly as well as outward movementh without the employment of a spacer. v

Figs..7 and 9 of the drawing illustrate a form of' the invention wherein the head I2au is shaped or provided with means for holding thev disc I3 against inward movement. In this form ofthe `invention the container kbody I0, the disc'I3' and/.fl

ating with the under side of the disc I3 adiacenti? its periphery. In practice this part of the head I2a may be in the nature of a raised or embossed ridge. In `the drawing I have illustrated the major portion of the head I2=^ embossed or raised so that the disc I3 rests directly on it. Thedisc I3 has its peripheral portion held between the flange 29 -and the head Iza and is prevented from moving 'either inwardly or outwardly and the ange 23 serves to prevent lateral shifting of the disc. The embossing or raising of the major portion of ythe'head |22, as just described, provides or leaves an annular groove 35 at the inner'side of the flange 25. 'I'he inner part 28 of themet'af ring l5 is received in this annular groove 35.

The present invention provides a container closure construction embodying an outer member or disc I3 or I 3a that is dependably retained in place in spaced relation to the bodyor head I2 of the closure withoutresorting to the use of padding, adhesive or a central support. It is to be particularly noted that the top 'closure does not have any exposed corners or edges.` The rim 30 may lie substantially flush with the upper surface of the disc 'I3 or I3a and 'joins the flange 29 at a rounded corner.` The part' 21 of the rim f 30 is round and smooth where it engages about the edgel of the riml 26. 'Ihe flange 29 of the metal ring I5 has iirm holding engagement with the peripheral portion of the disc I3 or I3E- to dependably hold the same against movement and loss.
